Long-term vs short-term
A long-term capital gain (held 12+ months past the basis-setting event) gets preferential federal rates: 0%, 15%, or 20% depending on total taxable income, plus 3.8% NIIT for MAGI above $200k single. Short-term gains are taxed at ordinary rates up to 37% federally, plus state. For this $750,000 gain, the short-term total would run approximately $380,207, compared with $246,080 long-term. The difference is roughly $134,127.
New York's treatment
New York taxes long-term gains at ordinary income rates. At the top bracket, that's 10.9%. No state preference for long holding periods.
Cost basis considerations
For RSU shares, basis equals the vest-date closing price. For ISO shares (qualifying disposition), basis equals strike plus any ordinary-income component at exercise. For ESPP shares, basis depends on whether the sale is a qualifying or disqualifying disposition. These basis rules materially affect whether a reported gross sale amount is mostly gain or mostly return of basis.
